[PATCH rcu 04/27] arch/powerpc/kvm: Remove "select SRCU"

Now that the SRCU Kconfig option is unconditionally selected, there is no longer any point in selecting it. Therefore, remove the "select SRCU" Kconfig statements. Signed-off-by: Paul E. McKenney Cc: Michael Ellerman Cc: Nicholas Piggin Cc: Christophe Leroy Cc: --- arch/powerpc/kvm/Kconfig

[PATCH v2] powerpc: Fix a wrong version calculation issue in ld_version

** The Issue ** The ld_version() function seems to compute the wrong version value for certain ld versions like the following: $ ld --version GNU ld (GNU Binutils; SUSE Linux Enterprise 15) 2.37.20211103-150100.7.37 For input 2.37.20211103, the value computed is 20234803 which is way more th

[PATCH 07/14] powerpc/vdso: Improve linker flags

When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, there are several warnings in the PowerPC vDSO: clang-16: error: -Wl,-soname=linux-vdso32.so.1: 'linker' input unused [-Werror,-Wunused-command-line-argument] clang-16: error: -Wl,--hash-style=both: 'linker' input unused [-Werr

[PATCH 06/14] powerpc/vdso: Remove unused '-s' flag from ASFLAGS

[PATCH 00/14] Remove clang's -Qunused-arguments from KBUILD_CPPFLAGS

Hi all, Clang can emit a few different warnings when it encounters a flag that it recognizes but does not support internally. These warnings are elevated to errors within {as,cc}-option via -Werror to catch unsupported flags that should not be added to KBUILD_{A,C}FLAGS; see commit c3f0d0bc5b01 ("
